rendering 'all-geometry' featureset (points, lines and polygons) in map control

Is it possible to have an 'all-geometry' featurset (one that holds all geometries: points, lines and polygons) rendered into the map control?

Given that any geometry can be stored in MS SQL Server or PostGIS tables and exported to a datatable with a geography (or geometry) datatype column, it would be helpful to be able to render the features in a layer without first having to filter by geometry
type ... in the same way as is done in the MSSS Spatial tab in MSSS Management Studio.
